This is a C# extension method that allows you to perform a search operation on a collection of objects represented by IQueryable<T>
. The search is performed based on specific properties of the objects.

Using the Extension Method:
using AveryBusiness; using System.Linq; // Your IQueryable<T> source IQueryable<YourType> source = ...; // Define search parameters string searchQuery = "YourSearchQuery"; string[] searchParameters = { "Property1", "Property2.NestedProperty" }; // Properties to search // Perform the search var result = source.Search(searchQuery, searchParameters).ToList();
Replace
YourType
,"Property1"
,"Property2.NestedProperty"
, and"YourSearchQuery"
with appropriate types, property names, and search query.
- source: The
IQueryable<T>
representing the collection of objects to search within. - search: The string to search for within the specified properties.
- parameters: An array of strings representing the names of the properties to search within. Nested properties can be specified using dot notation (e.g.,
"Property1.NestedProperty"
).
The extension method Search<TSource>()
dynamically generates a predicate expression based on the search query and properties specified. It builds an expression tree that represents the search condition and applies it to filter the IQueryable<T>
source.
The method SearchPredicate<T>()
generates the main predicate expression, while PredicateFromProperties<T>()
creates individual expressions for each property specified in the search parameters.
